Alright, I'll scale back a little. How do the GBRs act around the tetras? Do they ever attack them?
Also, if I only select fish under 2" (except for the bettas and maybe GBRs) how many overall do you think would be a good number? I know 'one inch per gallon' works okay as a basic measuring stick for itty bitty fish...
My adventures in keeping Indostomus crocodilus, the crocodile toothpick fish. AKA armored stickleback, paradox fish, and freshwater pipefish. Care is (to the best of my knowledge) exactly the same as Indostomus paradoxus.
